Title: Binder strap tool
IPC: B65B13/02
Filed: 1963-03-07
Abstract: 1,031,684. Strapping bundles &c. PANDUIT CORPORATION. March 7, 1963 [March 8, 1962], No. 9077/63. Heading F2G. A tool for tensioning a strap comprises two jaw members 7, 8 joined together to provide relative movement between them, the first jaw member having means 2a to restrain movement of one end of the strap, the second jaw member having means 17 for gripping the other end of the strap, the relative movement in one direction between the jaw members covering the strap to be tensioned, a shear blade 11 mounted for movement adjacent the jaw member 7, an actuator for the blade 11 and bias means 27, 28 to prevent the actuator from actuating the blade until a predetermined tension is reached in the strap. The end of the strap of which the movement is restrained has a sleeve 2a which restrains it, as disclosed in Specification 989,984. The binding strap 2 is passed around the bundle 3 to be strapped, through a passage formed between two walls at the end of the jaw member 7, through a recess 16 in the jaw member 8 and across a toothed gripper 17 which is biased by a spring 19 to turn about a pivot 18 towards the jaw member 7 but held back, when the jaw members are together, by a projection 31 from the jaw member 7. The jaw members extend to handles 4. 5 and are pivoted together by a pin which also passes with clearance through a shear blade actuator having teeth 24a. This shear blade actuator is held in a recess 21 in the jaw member 8 and has a screw-threaded end which passes through two yokes 25, 26. A nut 29 on the threaded end of the actuator 24 adjusts the compressive force of springs which tends to keep the actuator in a position in which teeth 24a on the end thereof are disengaged from teeth 11a on the lower portion of the shear blade 11. When the handles 4, 5 are moved towards one another the projection 31 moves away from the gripper 17 which rotates so that its teeth 17a grip the strap end 2b, which is pulled, as the handles 4, 5 continue to converge, so that the strap 2 is tightened around the bundle 3. When the strap is tensioned to a degree corresponding to the bias provided by the springs the shear blade actuator is caused to be moved towards the shear blade 11 and the teeth 11a thereon are engaged by the teeth 24a and, as the handle movement continues, the actuator 24, which is rigid with the handle 5, pivots on its pin and raises the shear blade 11.

Title: Cephem compounds
IPC: C07D501/12
Filed: 1972-02-28
Abstract: 1359092 Cephalosporin C derivatives TAKEDA YAKUHIN KOGYO KK 28 Feb 1972 [26 Feb 1971 (2) 17 Aug 1971] 9088/72 Headings C2A and C2C The novel compound 7-[D-5<SP>1</SP>-(isobornyloxycarbonylamino) - 5<SP>1 </SP>- carboxyvaleramido]- cephalosporanic acid is prepared by reacting cephalosporin C with isobornyloxycarbonyl chloride or 1 - isobornyloxycarbonylpyridinium chloride in which the pyridine ring may be substituted at the 2- or 4-position by one or more electron-donating groups (e.g. amino, alkylamino or hydroxy). The reaction is carried out in aqueous or aqueous-organic solvent, preferably in the presence of a base. The product is precipitated by bringing the reaction mixture to the iso-electric point of the product, i.e. pH 1-3. The production of the isobornyl derivative may be used as a means for recovering cephalosporin C from its impure solutions (e.g. fermentation broths), the derivative being subsequently hydrolysed with strong aqueous acid or base or anhydrous trifluoracetic acid, to cephalosporin C. Alternatively the derivative may be esterified and then de-acylated (e.g. via the imino halide and imino ether) to yield a 7- aminocephalosporanic acid ester which is deesterified to 7-aminocephalosporanic acid. Isobornyloxycarbonyl chloride is prepared by reacting isoborneol with phosgene; the chloride is subsequently reacted with 4-dimethylaminopyridine to give 1-isobornyloxycarbonyl-4-dimethylaminopyridinium chloride.

Title: Improvements in and relating to radar displays
IPC: G01S13/538
Filed: 1947-04-03
Abstract: 632,689. Photo-electric apparatus. HARRIS, K. E., and COURT, G. W. G. April 3, 1947, No. 9131. [Class 40 (iii)] [Also in Group XL (c)] A photo-cell 5 is employed to view the screen of a cathode-ray tube 2 producing a plan-position display and forming part of a radar system for observing airfield surfacemovements [see Group XL (c)]. During each scan of the radar the cell generates a video signal train representative of the displayed responses, the responses from certain selected areas such as the runways and perimeter track, being eliminated by means of a mask 6, 6a. The masked signal train is delayed in circuit 8 by an integral multiple of the scan period and then applied to mixer 9 in opposition to the normal video signal train obtained direct from the radar receiver 4 over lead 10. The resulting signal produces the main plan-position display on cathode-ray tube 1. By this means stationary object or clutter response is eliminated from the main display except over the masked areas where it is necessary to observe both stationary and moving objects.

A semi-conductor rectifier assembly comprises a plurality of semi-conductor rectifier units electrically connected between two opposed conductor bars, at least one of which is hollow for at least part of its length to provide a duct for the transmission of cooling fluid. As shown, in a rectifier assembly which may be used as one branch of a multi-phase rectifying network, four groups of six rectifier units are connected in parallel between copper conductor bars 13, 14, in each of which an internal duct 19 or 20 extends from the end of the conductor connected to a bus-bar 17 or 18 for approximately half the length of the conductor. Rectifier units, in groups 25-30 and 31-36, preferably comprise germanium or silicon rectifying elements and are connected between one of the conductor bars 13, 14 and upstanding distance-pieces 23 on one face of a panel 10 of insulating material, the connections to the other conductor bar being completed through pairs of parallel connected fuse links 37, the relative positions of fuse links for the two sets of rectifier units being varied so that each unit is nearer the bar which, at that point in its length, carries the smaller current in operation. Each rectifier unit comprises two cooling chambers, and cooling fluid, normally water, is supplied through a main 44 and a flexible connection 45 to duct 19 in conductor bar 13, whence it passes via connections 47 and 53 to the two sets of rectifier units, flowing serially through the cooling chambers of the units of each set and finally entering duct 20 in bar 14 to be drained off at 52. Two further sets of rectifier units and fuse links are similarly connected to the conductor bars on the remote side of panel 10, and these units are cooled in the same manner as that described for the visible units. The duets 19, 20 may be formed in the copper conductor bars during casting or by subsequent drilling; alternatively, solid aluminium bars, cast around copper pipes, may be used.
